Bradford Park Avenue FC is a former English League club from the city of Bradford, West Yorkshire.  The club was formed in 1863 as the Bradford Football Club. They then became founder members of the Northern Rugby Football Union following a dispute between Northern clubs and the Rugby Football Union over the payment of expenses in 1895. They won the Championship in 1903–04 and the Challenge Cup in 1905–06.   After a failed bid to merge with Bradford City, a professional football team was established in 1907. Although throughout its history the club was officially Bradford AFC, the name of the ground, Park Avenue, was usually added in brackets to avoid confusion with other teams playing in the city.  They joined the Southern League, even though the club was based in the north, filling a gap left by Fulham who had been successful in joining the Football League. In 1908, they were elected to the Second Division of the Football League and were promoted to the First Division in 1913 after finishing as runners-up. They achieved their highest ever league position of 9th at the end of the 1914–15 season.  

After WWI the club began a steady decline. Relegation to the Second Division in 1921 was followed by a drop to the Third Division North the following season.  In 1928 the club finished as Champions, and was  promoted back to the Second Division where they remained until relegated again in 1950. They were  then placed in the Fourth Division after reorganisation in 1958 where they struggled until  they were voted out of the Football League in 1970 and replaced by Cambridge United. The club dropped into the Northern Premier League, and financial problems meant they had to sell Park Avenue in 1973 and ground share with neighbours Bradford City. However, the sale did not solve the difficulties, and the club went into liquidation on 3 May 1974 with debts of £57,652. They were immediately re-formed as a Sunday league club playing in the league club's former colours.
